[0016] like Figures 1 to 3 As shown in the figure, the safety inspection and warning device for power facilities proposed in this embodiment includes: The storage box 1 has an opening at the top and a cover 101 that is in contact with it. A U-shaped handle is fixedly connected to the top of the cover 101. A rectangular support rod 102 is fixedly connected to the bottom of the cover plate 101, and the storage box 1 is slidably sleeved on the rectangular support rod 102; wherein a rectangular guide hole is opened on the bottom inner wall of the storage box 1 to slide and fit with the outer side of the rectangular support rod 102, so as to allow the rectangular support rod 102 to pass through and guide its vertical sliding. The warning and prompting component is fixedly connected to the bottom of the cover plate 101 and the front side of the rectangular support rod 102; The lower support 3 is located below the storage box 1. It has mounting slots with openings at the top and bottom on all four sides. An expansion support rod 302 is rotatably installed between the inner walls of the two sides of the mounting slot. The double-point opposite thread drive assembly is fixedly connected to the top of the lower support 3. The rectangular support rod 102 is threaded onto the double-point opposite thread drive assembly. The bottom four sides of the double-point opposite thread drive assembly are hinged with inclined connecting rods 304. The two opposite connecting rods 304 are symmetrically arranged. The bottom of the four extended support rods 302 on the same side is respectively hinged to the bottom end of the corresponding connecting rod 304. The drive motor 405 is embedded and fixed on the top of the lower support 3, and its output shaft is fixedly connected to the double-point opposite thread drive assembly. The double-point opposite thread drive assembly is used to drive the rectangular support rod 102 to move upward and the four connecting rods 304 to rotate downward when the drive motor 405 is started, or to drive the rectangular support rod 102 to move downward and the four connecting rods 304 to rotate upward, so that the rectangular support rod 102 and the connecting rods 304 move in opposite directions. The warning and prompting assembly is used to move upward when the rectangular support rod 102 moves upward, so as to provide safety warnings during inspection and maintenance. The four extended support rods 302 are used to synchronously rotate outward to the horizontal when the four connecting rods 304 rotate downward to perform extended anti-tilting support work. In this embodiment, a stainless steel shaft 301 is fixedly connected between the inner walls of the two sides of the mounting groove. A first circular hole is opened at the bottom of one side of the expansion support rod 302. A first bearing is fixedly fitted in the first circular hole. The inner ring of the first bearing is fixedly fitted to the outer side of the corresponding stainless steel shaft 301. Anti-slip pads are glued and fixed on the opposing sides of the two opposing expansion support rods 302. The stainless steel shaft 301 and the first bearing serve to rotate and install the expansion support rod 302.

[0017] Furthermore, such as Figure 2 As shown, the warning and prompting component includes a warning light 201, two LED lights 202 and a warning sign 2, which are installed in the storage box 1. The warning light 201 is fixedly connected to the top front side of the rectangular support rod 102. The warning sign 2 is located below the warning light 201 and is fixedly connected to the front side of the rectangular support rod 102. A reflective warning sticker is glued to the front side of the warning sign 2. The two LED lights 202 are located above the front of the warning sign 2 and are fixedly connected to the bottom of the cover plate 101. In this implementation scheme, the warning light 201, two LED lights 202, and warning sign 2 work together to move the cover plate 101 upward when the rectangular support rod 102 moves upward. At this time, the rectangular support rod 102 and the cover plate 101 work together to drive the warning light 201, two LED lights 202, and warning sign 2 upward. Personnel can then turn on the warning light 201 and two LED lights 202. The warning light 201 is used to provide a safety warning in the direction away from the maintenance position, and the two LED lights 202 illuminate the reflective warning sticker on the front of the warning sign 2 to further warn personnel, achieving the effect of providing a safety warning during maintenance. Subsequently, the rectangular support rod 102 is used to move downward to drive the warning light 201, two LED lights 202, and warning sign 2 downward and store them in the storage box 1, achieving the effect of safe storage and protection of the warning items when not in use, and improving the safety of the warning items when not in use.

[0018] Furthermore, such as Figure 1 and 2As shown, the dual-point opposite thread drive assembly includes a fixed box 4, a first gear 401, two second gears 403, a first screw 402, two second screws 404, and a loop-shaped lifting plate 303. The fixed box 4 is fixedly connected to the top of the lower support 3. The front and bottom of the fixed box 4 are both open. The first screw 402 and the two second screws 404 are rotatably fitted into the top of the fixed box 4. The first gear 401 is located inside the fixed box 4 and is fixedly connected to the bottom end of the first screw 402. The two second gears 403 are respectively fixedly connected to the bottom ends of the corresponding second screws 404. The first gear 401 meshes with the two second screws 404. Between gears 403, the top ends of the two second screws 404 are rotatably connected to the bottom of the storage box 1. A rectangular support rod 102 is threaded onto the first screw 402. A spiral lifting plate 303 is threaded onto the two second screws 404. The rectangular support rod 102 is located inside the spiral lifting plate 303 and does not contact its inner side. The four sides of the bottom of the spiral lifting plate 303 are respectively hinged to the top ends of the corresponding connecting rods 304. The bottom of the first gear 401 is fixedly connected to the top end of the output shaft of the drive motor 405. A venting baffle is fixedly installed on the front side of the fixed box 4 by four screws. The front side of the venting baffle is provided with multiple vent holes. In this embodiment, tool placement boxes 5 are fixedly connected to the top four sides of the U-shaped lifting plate 303, and are in movable contact with the bottom of the storage box 1. The top of the tool placement box 5 is set as an opening, and the tool placement box 5 is used to assist personnel in placing loose parts or tools. The bottom end of the rectangular support rod 102 has a first threaded hole that is threadedly connected to the first screw 402. The bottom of the U-shaped lifting plate 303 has two second threaded holes that are respectively threadedly connected to the corresponding second screw 404. The threaded connection between the first screw 402 and the first threaded hole facilitates the vertical displacement of the rectangular support rod 102 when the first screw 402 rotates. The threaded connection between the second screw 404 and the second threaded hole facilitates the upward and downward displacement of the boom lifting plate 303 when the second screw 404 rotates. The top of the fixing box 4 has three second circular holes, each containing a second bearing. The outer sides of the first screw 402 and the second screw 404 are respectively fixedly connected to the inner rings of the corresponding second bearings, enabling the rotational installation of the first screw 402 and the second screw 404. The bottom of the storage box 1 is fixedly connected to two third bearings, the inner sides of the inner rings of the third bearings being fixedly connected to the outer sides of the corresponding second screw 404, enabling the rotational installation of the second screw 404. In this embodiment, the fixed box 4, the first gear 401, the two second gears 403, the first screw 402, the two second screws 404, and the loop-shaped lifting plate 303 work together to start the drive motor 405 in the forward direction, causing the first gear 401 to rotate. The first gear 401 drives the first screw 402 to rotate, and the rotation of the first screw 402 causes the rectangular support rod 102 to move upward. When the first gear 401 rotates, it drives the two second gears 403 meshing with it to rotate in the opposite direction. The two second gears 403 drive the two second screws 404 to rotate in the opposite direction, so that the rotation direction of the second screws 404 is opposite to that of the first screws 402. The rotation of the two second screws 404 causes the loop-shaped lifting plate 303 to move downward. 303 drives the four connecting rods 304 to rotate downwards; when the drive motor 405 is started in reverse, the movement direction is completely opposite to that of the drive motor 405 started in the forward direction. At this time, the rectangular support rod 102 moves downwards, and the loop-shaped lifting plate 303 moves upwards and drives the top of the four connecting rods 304 to rotate upwards. Based on the principle that the two second gears 403 mesh with the first gear 401 and form opposite rotations when rotating, the second screw 404 and the first screw 402 always rotate in opposite directions. This achieves the effect of driving the rectangular support rod 102 to move upwards and the four connecting rods 304 to rotate downwards when the drive motor 405 is started, or driving the rectangular support rod 102 to move downwards and the four connecting rods 304 to rotate upwards. During use, the rectangular support rod 102 moves upward to drive the warning piece out, and the four connecting rods 304 rotate downward to drive the four extended support rods 302 to rotate outward synchronously to a horizontal position for extended support and anti-tipping work, improving the support stability during use and reducing the risk of tipping. After use, the four connecting rods 304 rotate upward to pull the four extended support rods 302 upward to fold them to the outside of the storage box 1. This achieves the effect of folding the four extended support rods 302 upward in one piece when storing and protecting the warning piece after use, reducing the space occupied when not in use and making it convenient for personnel to carry and work.

[0019] Furthermore, a lithium battery located behind the warning sign 2 is fixedly installed on the inner left side of the storage box 1, and the warning light 201, LED lighting 202 and drive motor 405 are all electrically connected to the lithium battery.

[0020] It should be noted that: the warning light 201 and the two LED lights 202 are equipped with the same on / off switch. The on / off switch is preferably installed at the bottom of the cover plate 101 so that personnel can press it after the cover plate 101 is raised. The drive motor 405 is equipped with a control switch, which is preferably installed on the right side of the fixed box 4. The on / off switch and the control switch are electrically connected to the corresponding components and the lithium battery through flexible wires. The lithium battery is preferably a Lunqu Technology P760S model lithium battery with integrated charge and discharge protection function. This model of lithium battery can provide safe power supply to the warning light 201, the LED lights 202 and the drive motor 405. Furthermore, the technical solution of using a flexible wire to power a lithium battery and cooperating with a corresponding switch to allow personnel to control the opening and closing of electrical components is a well-known and mature technology in this field. Its specific working principle and conventional flexible wire connection method will not be elaborated here. In addition, since the warning light 201 and the two LED lights 202 are moving parts, the flexible wires connecting them are conventionally designed with a certain bending length reserved to meet their displacement requirements.

[0021] The usage method of this embodiment is as follows: When using the safety inspection and warning device for power facilities, place the device outside the maintenance area of ​​the power facility, start the drive motor 405 in the forward direction to drive the first gear 401 to rotate. The first gear 401 drives the first screw 402 to rotate. The rotation of the first screw 402 drives the rectangular support rod 102 to move upward. When the first gear 401 rotates, it drives the two second gears 403 meshing with it to rotate in the opposite direction. The two second gears 403 drive the two second screws 404 to rotate in the opposite direction, so that the rotation direction of the second screws 404 is opposite to that of the first screws 402. The rotation of the two second screws 404 drives the U-shaped lifting plate 303 to move downward. The U-shaped lifting plate 303 drives the four connecting rods 304 to rotate downward. The upward movement of the rectangular support rod 102 drives the cover plate 101 to move upward. At this time, the rectangular support rod 102 and the cover plate 101 work together to drive the warning light 201 and the two LED lights 20 2. The warning sign 2 moves upward, and personnel can turn on the warning light 201 and two LED lights 202. The warning light 201 is used to provide a safety warning in the direction away from the maintenance position, and the two LED lights 202 are used to illuminate the reflective warning sticker on the front of the warning sign 2 to further warn personnel and achieve the effect of safety warning during maintenance. The four connecting rods 304 are rotated downward to drive the four expansion support rods 302 to rotate outward synchronously to the horizontal to expand the support and prevent tilting. This allows the warning item to be removed for use and the lower expansion support to prevent tilting in one piece, reducing the risk of accidental tipping and improving the stability of the support when the warning is in use. In addition, when the U-shaped lifting plate 303 moves downward, it also causes the four tool placement boxes 5 to move downward and separate from the storage box 1, removing the obstruction on the top of the tool placement boxes 5, allowing personnel to take and put in loose parts or tools, and achieving the effect of conveniently placing loose parts or tools in one piece. After use, the operator reverses the start of the drive motor 405, which moves in the opposite direction to the forward start of the drive motor 405. At this time, the rectangular support rod 102 moves downward, and the U-shaped lifting plate 303 moves upward, causing the tops of the four connecting rods 304 to rotate upward. When the U-shaped lifting plate 303 moves upward, it causes the four tool storage boxes 5 to contact the bottom of the storage box 1, thus covering the top of the tool storage boxes 5 to prevent tools from falling out. The downward movement of the rectangular support rod 102 drives the warning light 201 and the two LED lights. 202 and warning sign 2 are moved down and stored in storage box 1 to provide safe storage and protection for the warning items when not in use. The four connecting rods 304 rotate upward and pull, causing the four expansion support rods 302 to rotate upward and fold to the outside of storage box 1. This achieves the effect of storing and protecting the warning items after use and automatically folding the four expansion support rods 302 in one piece. This reduces the risk of accidental damage to the warning items when they are exposed and carried when not in use, improves the safety of the warning items when not in use, and reduces the space occupied at the bottom, making it convenient for personnel to carry and work safely.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
